About Katherine A Keith

About the Provider

Practicing medicine requires a personalized approach to every patient. You can’t just look in a textbook or search online. You have to listen actively, be curious, and have a deep sense of compassion. That is that care that I strive to provide to every patient.

My perspective is holistic. You are more than your body, and your health isn’t just physical. I’m here to care for your whole self—physical, mental, and otherwise. I emphasize lifestyle medicine in my practice, meaning I try to help patients improve their health and reduce their reliance on medications through strategies like better diet, better exercise, better sleep, and natural remedies where appropriate. I’m also passionate about helping people treat hormone deficiencies or imbalances through bioidentical hormone therapy.

I love that family medicine allows me to get to know who may patients really are, and even work with multiple generations of the same family. It’s deeply satisfying to have that “Aha!” moment after finding the solution to a tough medical problem, and then see how that solution makes a difference in someone’s life.
